I was an army officer who resigned with an impeccable record after Iraq.
I would not recommend military service unless more of these conservative windbags start serving. If not, you will just feel like you are being used by contractors and politicians. There is no worse feeling than having a rich, healthy, 22-year-old young man with a trust fund thanking you for your service; like you're his butler. Deep down, he's thinking "service is for suckers". The army is no longer some democratic cross section of American society. It has devolved into a braindead constabulary force; similar to mall cops or prison guards. I hate to say it. I saw a lot of very intelligent soldiers in the lower ranks and they all looked utterly miserable.
If you insist on serving, try the Air Force, Navy, or Marines first. The army is terrible and thrives on incompetence. It has a hyper-conservative mantra and is borderline mutinous under Democratic presidents.
